The available positions for your modules are defined in the templates/your_template/index.php file inside your Joomla directory. You can create a custom position by adding it into this file. For example, if you want to create a position named “custom”, you should add the following code into the index.php file where you want the module to be displayed:
<?php if ($this->countModules(‘custom’)) : ?>
<div>
<jdoc:include type=”modules” name=”custom” style=”xhtml” />
</div>
<?php endif; ?>
now open the template.xml and add the position as <position> moduleposition name </position>
enjoy 🙂
